of deep environments in the Skagerrak by ROV-techniques -
fauna and environmental threats
of conventional sampling have indicated change and deterioration
of deep communities in the northern Skagerrak over the last
decades. This project is aimed at assessing the present status
of primarily deep rocky-bottom biotopes along the Koster-Väderö
and nothern Skagerrak trough, as a basis for future comparison,
and to identify possible causes for change, such as changed
fishing practises, eutrophication and influence of toxic substances.
The possible need for protective measures is evaluated, and
biotopes of particular interest or value are
mapped with GIS-techniques. The project is also aimed at the
development of new photographic and acoustic techniques for
surveys and detailed studies of deep benthic communities, as
an alternative to conventional destructive sampling techniques.
